Dunno what Suzuki are playing at. My mate's got a Suzuki 125cc scooter. Even that's got FI. But they could never instal it on the GZ. Oh well..... :??:
Remember that the carb is the achilles heel of an otherwise decent GZ. You'll find that once you get it running, you'll need regular doses of carb cleaner in the tank to keep it in tip top order.
